If you want to prevent a user logon script from running on a specific Windows Server 2003 computer, like a Terminal Server, you can prevent the Userinit.exe process from running it, by altering the Userinit Value Name at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon and by setting the UserInitLoginScript variable to null:
1. Save the following to a \FolderName\DisableLogonScript.cmd file:
@echo off
Set UserInitLogonScript=
Start %systemroot%\system32\userinit.exe
exit
2. Open a CMD.EXE window.
3. Type the following command and press Enter:
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /V Userinit /T REG_SZ /F /D "\FolderName\DisableLogonScript.cmd"
NOTE: \FolderName\ is the drive letter and folder path where you saved the DisableLogonScript.cmd file.
